Node.js Http2ServerRequest.method用法及代码示例

Http2ServerRequest.method是http2模块内的Http2ServerRequest类的内置应用程序编程接口，用于获取请求方法的字符串表示形式。

用法:

const request.method

参数：此方法不接受任何参数作为参数。

返回值：此方法返回请求方法的字符串表示形式。

如何生成私钥和公共证书？

1.文件名：私钥

打开记事本和copy-paste下面的项并将文件另存为private-key.pem

2.文件名：公开证书

打开记事本和copy-paste下面的项并将文件另存为public-cert.pem

范例1： 文件名：index.js

Javascript

// Node.js program to demonstrate the 
// Http2ServerRequest.method method 
  
const http2 = require('http2'); 
const fs = require('fs'); 
  
// Private key and public certificate for access 
const options = { 
  key:fs.readFileSync('private-key.pem'), 
  cert:fs.readFileSync('public-cert.pem'), 
}; 
  
// Request and response handler 
const http2Handlers = (request, response) => { 
  
  // Getting method of http2  
  // by using request.method method 
  const auth = request.method; 
  console.log("request method:- " + auth) 
}; 
  
// Creating and initializing server 
// by using http2.createServer() method 
const server = http2.createServer(options, http2Handlers); 
  
server.on('stream', (stream, requestmethod) => { 
  stream.respond({ ':status':200, 'content-type':  
  'text/plain' }); 
  stream.write('hello '); 
  
  // Getting all information of this http2stream object 
  // by using state method 
  const status = stream.state; 
  
  stream.end("priority weight:" + status.weight); 
  
  // Stopping the server 
  // by using the close() method 
  server.close(() => { 
    console.log("server destroyed"); 
  }) 
}); 
  
server.listen(8000); 
  
// Creating and initializing client 
// by using tls.connect() method 
const client = http2.connect('http://localhost:8000'); 
  
const req = client.request({  
  ':method':'GET', ':path':'/' }); 
  
req.on('response', (responsemethod) => { 
  console.log("status:" 
  + responsemethod[":status"]); 
}); 
  
req.on('data', (data) => { 
  console.log('Received:%s ', 
  data.toString().replace(/(\n)/gm,"")); 
}); 
  
req.on('end', () => { 
  client.close(() => { 
    console.log("client destroyed"); 
  }) 
});

使用以下命令运行index.js文件：

node index.js

输出：

request method:- GET
status:200
Received:hello
Received:priority weight:16
client destroyed
server destroyed

范例2： 文件名：index.js

Javascript

// Node.js program to demonstrate the 
// Http2ServerRequest.method method 
  
const http2 = require('http2'); 
const fs = require('fs'); 
  
// Private key and public certificate for access 
const options = { 
  key:fs.readFileSync('private-key.pem'), 
  cert:fs.readFileSync('public-cert.pem'), 
}; 
  
// Request and response handler 
const http2Handlers = (request, response) => { { 
  
  // Getting method of http2  
  // by using request.method method 
  const auth = request.method; 
  response.end("request method:- " + auth) 
}}; 
  
// Creating and initializing server 
// by using http2.createServer() method 
const server = http2.createServer(options, http2Handlers); 
  
server.on('stream', (stream, requestHeaders) => { 
  
  // Getting all information of this http2stream object 
  // by using state method 
  const status = stream.state; 
  
  stream.end("The sum weight of all Http2Stream:" +  
  status.sumDependencyWeight); 
    
  // Stopping the server 
  // by using the close() method 
  server.close(() => { 
    console.log("server destroyed"); 
  }) 
}); 
  
server.listen(8000); 
  
// Creating and initializing client 
// by using tls.connect() method 
const client = http2.connect('http://localhost:8000'); 
  
const req = client.request({  
  ':method':'GET', ':path':'/' }); 
  
req.on('data', (data) => { 
  console.log('Received:%s ', 
  data.toString().replace(/(\n)/gm,"")); 
}); 
  
req.on('end', () => { 
  client.close(() => { 
    console.log("client destroyed"); 
  }) 
});

使用以下命令运行index.js文件：

node index.js

输出：

Received:request method:- GET
client destroyed
server destroyed
